A method of using a liner assembly comprises inserting the liner assembly into a wellbore, the liner assembly having an annular packer and a port collar. The method further comprises closing fluid flow through a lower end of the liner assembly, actuating the annular packer into engagement with the wellbore, and actuating the port collar into an open position to open fluid communication between an interior of the liner assembly and the wellbore. The method further comprises pumping cement into the wellbore through the port collar at a location above the annular packer and actuating the port collar into a closed position to close fluid communication between the interior of the liner assembly and the wellbore.

1. A method of using a liner assembly, comprising: inserting the liner assembly into a wellbore, wherein the liner assembly includes an annular packer and a port collar;closing fluid flow through a lower end of the liner assembly;actuating the annular packer into engagement with the wellbore;actuating the port collar into an open position to open fluid communication between an interior of the liner assembly and the wellbore, wherein the port collar is actuated into the open position after the annular packer is actuated into engagement with the wellbore, and wherein the port collar is actuated into the open position using a coded pressure pulse;pumping cement into an annulus of the wellbore surrounding the liner assembly through the port collar at a location above the annular packer;actuating the port collar into a closed position to close fluid communication between the interior of the liner assembly and the wellbore;actuating a swivel of the liner assembly to rotationally decouple an upper portion of the liner assembly from a lower portion of the liner assembly; androtating the port collar while cement is pumped into the annulus of the wellbore surrounding the liner assembly, wherein the swivel is positioned below the port collar. 2. The method of claim 1, further comprising rotating the upper portion of the liner assembly above the swivel to help distribute cement within the annulus of the wellbore surrounding the liner assembly. 3. The method of claim 1, further comprising actuating the port collar into the closed position using at least one of a hydraulic, pneumatic, electric, and mechanical force. 4. The method of claim 1, further comprising actuating the port collar into the closed position using a radio frequency identification tag. 5. The method of claim 1, further comprising actuating a liner hanger of the liner assembly into engagement with the wellbore prior to pumping cement into the wellbore. 6. The method of claim 1, further comprising actuating a liner packer of the liner assembly into engagement with the wellbore after pumping cement into the wellbore. 7. The method of claim 1, wherein the liner assembly is used to drill the wellbore and then cemented within the wellbore in a single trip into the wellbore. 8. A method of using a liner assembly, comprising: lowering the liner assembly into a wellbore, wherein the liner assembly includes an annular packer, an upper port collar, and a lower port collar;actuating the annular packer into engagement with the wellbore;actuating one of the upper and lower port collars into an open position to open fluid communication between an interior of the liner assembly and the wellbore, wherein the upper or lower port collar is actuated into the open position using a coded pressure pulse;pumping cement into an annulus of the wellbore surrounding the liner assembly through the upper or lower port collar;actuating the upper or lower port collar into a closed position to close fluid communication between the interior of the liner assembly and the wellbore;actuating a swivel of the liner assembly to rotationally decouple an upper portion of the liner assembly from a lower portion of the liner assembly; androtating at least one of the upper and lower port collars while cement is pumped into the annulus of the wellbore surrounding the liner assembly, wherein the swivel is positioned below at least one of the upper and lower port collars. 9. The method of claim 8, further comprising actuating the upper or lower port collar into the closed position using at least one of a hydraulic, pneumatic, electric, and mechanical force. 10. The method of claim 8, further comprising actuating the upper or lower port collar into the closed position using a radio frequency identification tag. 11. The method of claim 8, further comprising drilling the wellbore using the liner assembly. 12. The method of claim 8, wherein actuating one of the upper and lower port collars comprises actuating the upper port collar, and further comprising: actuating the lower port collar into an open position to open fluid communication between the interior of the liner assembly and the wellbore;pumping cement into the wellbore through the lower port collar; andactuating the lower port collar into a closed position to close fluid communication between the interior of the liner assembly and the wellbore. 13. The method of claim 12, further comprising actuating the lower port collar into the open position using at least one of a hydraulic, pneumatic, electric, and mechanical force. 14. The method of claim 12, further comprising actuating the lower port collar into the open position using a coded pressure pulse. 15. The method of claim 12, further comprising actuating the lower port collar into the closed position using at least one of a hydraulic, pneumatic, electric, and mechanical force. 16. The method of claim 12, further comprising actuating the lower port collar into the closed position using a radio frequency identification tag. 17. The method of claim 12, wherein the lower port collar is actuated into the open position and the closed position prior to actuating the upper port collar into the open position. 18. A liner assembly for use in a wellbore, comprising: a liner hanger;a liner packer positioned below the liner hanger;a port collar positioned below the liner packer, wherein the port collar is movable between an open position that opens fluid communication between an interior of the liner assembly and an annulus surrounding the liner assembly, and a closed position that closes fluid communication between the interior of the liner assembly and the annulus surrounding the liner assembly, and wherein the port collar is actuated into the open position using a coded pressure pulse;an annular packer positioned below the port collar, wherein the annular packer is configured to be actuated into engagement with the wellbore prior to the port collar being movable into the open position; anda swivel positioned above the annular packer and configured to rotationally decouple a portion of the liner assembly above the swivel from a portion of the liner assembly below the swivel, and wherein the swivel is positioned below the port collar such that the port collar can be rotated while cement is pumped into the annulus surrounding the liner assembly. 19. The assembly of claim 18, wherein the port collar is actuated into the closed position using at least one of a hydraulic, pneumatic, electric, and mechanical force. 20. The assembly of claim 18, wherein the port collar is actuated into the closed position using a radio frequency identification tag. 21. The assembly of claim 18, further comprising a running string, wherein the running string is releasable from the assembly when disposed within the wellbore. 22. The assembly of claim 18, further comprising a second port collar, wherein the second port collar is movable between an open position that opens fluid communication between the interior of the liner assembly and the annulus surrounding the liner assembly, and a closed position that closes fluid communication between the interior of the liner assembly and the annulus surrounding the liner assembly. 23. The assembly of claim 22, wherein the second port collar is actuated into the open position using a coded pressure pulse. 24. The assembly of claim 22, wherein the second port collar is actuated into the closed position using a radio frequency identification tag. 25. The assembly of claim 22, wherein the second port collar is positioned below the port collar.
